Sen. Bob Casey was among the 42 Democrats who voted to keep Sen. Joe Lieberman in the Democratic caucus Tuesday, backing the independent lawmaker's bid to keep his chairmanship of the Homeland Security Committee even after he actively campaigned for Republican John McCain in the presidential contest.

Not a big surprise, particularly as Barack Obama had advocated reconciliation.

The Washington Post caught up with Casey after the vote.

"It was a historic meeting, but I think we've got to move forward," he said. "We've got too much work to do to let this stand in our way."
